CLAY-CLEANER.

Speciication of Letters Patent.

`Patented Mar. 1"?, 1914.

Application filed Decenfoer 2, 1912. Serial No. 734,473.

To all whom it may conc-em Be it known that we, BERNARD JAoQUAn'r the United States, and residents, respec-v tively, of South River, in the county of Middlesex and State oi New Jersey, and the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful 1mprovements in Clay-Cleaners, ot which the following is a specification. y

rhis invention relates to clay cleaners and more. particularly to means tor providing an eilicient discharge of the pebbles which are fed to the hopper with the clay to be cut.

For this reason, the invention consists of an improved hopper, having a wall substantially in the shape of an involute, and an auxiliary wall substantially concentric or parallel therewith, which auxiliary wall does not extend clear down to the knives, butV only down to a short distance theretrom, the said distance larger than the diameter of the pebbles caught in the hopper with the clay.

In the accompanying drawings, Figure 1 is a plan view of our improved clay cleaner, with the improvement shown therein, Fig. 2 is a vertical transverse section taken on line 2-2 Fig. 1, Fig. 3 is an end view of the gate for accomplishing the discharge, Fig. a is a vertical detail section of a different enr bodiment, and Fig. 5 is a plan view of the same.

Similar characters of reference indicate corresponding parts throughout the several iigures of the drawing.

Referring to the drawings, and more particularly to Fig. 1, the trame work 10 is provided with the usual beams 11 to properly support the clay cleaner. A carrier 12 with radially arranged knives 13 rotates around the point 111: as a center, and causes the knives to pass beneath the hopper 15, which has its walls 16 and 17 arranged concentric with each other and either vertical or sloping to prevent the adhesion of the material, and which has an end wall 18 arranged substantially in the shape of an approximate involute, so as to permit any stones or pebbles or other material, striking the wall, to be deflected radially outward until they reach the end of the wall at the periphery of the carrier. Substantially concentric with the wall 18, a second or auxiliary wall 19 is provided,

which has its lowermost end a suitable distance from the knives, so as to permit the pebbles to pass between the knives and the lowest end of the wall. This opening` 20 thus formed is clearly shown in Fig. 8. The wall 18 of the hopper, however, extends in clase proximity to the knives, as is shown also in Fig. 3. As the material passes into thespace between the wall 19 and the wall 18 it has a less downward pressure acting thereon than the material in the hopper itself which is acted upon by the weight ot the entire mass of the hopper. The pebbles and other' material, gathered in between the walls 18 and 19, are thereby iree to move, and do not clog the knives. Then this matter so contained between the walls 18 and 19 is lgradually forced radially outwardly along the wall 18, it is moved on to a plate 21, which extends below a projecting plate 22 ot the carrier, and which directs this material out of the machine. To permit this, a door 25 movable in guide-ways 26 is provided which door on opening moves downwardly, and thereby may regulate the flow of the materials discharged from the clay cleaner. if this door is entirely o en, that is, in its lowermost position, the cischarge from the clay cleaner will be equal to the material entering the chamber between the walls 18 and 19, while, when the door is partially raised, this flow will be impeded to a considerable extent, so that bythe position of the door the flow may be varied. The door is provided with a U-shaped support 28 pivoted to a link 30, pivoted to a lever 31 at 32 which lever might be held in position by the fastening means 34 as is well known.

1n Fig. 4 is shown an exterior space-chamber formed by the wall 16 of the hopper 15 and the shortened involute wall 4:0 and the auxiliary involute el. r1`he free movement of the material in the outer space 42 prevents clogging.

We have shown several embodiments of our invention, but it is clear that changes may be made therein without departing from the spirit of the invention as dened by the appended claims.

Having thus described our invention, we claim as new and desire to secure by Letters Patent:

1. In a clay cleaner, a hopper having an involute endwall in proximity to the knives, and an auxiliary wall involute to said rst wall in advance thereof and having its lower edge below the plane of the top of the material .in the hopper, and distant from the knives to permit the passage of pebbles therebetween, whereby the material in the space between the walls is protected from the weight of the material in the main portion of the hopper.

2. In a clay cleaner, a hopper having an end wall in proximity to the knives, an auxiliary wall having its lowermost end distant from the knives, said hopper and auxiliary wall forming a space-chamber therebetween, an extension plate adapted to receive the material discharged from the chamber, and a verticallyemovable door permitting the discharge of the material on the plate.

3. In a clay cleaner, a carrier with knives, provided with an extension at its periphery,
